How can I fix the MMI screen on my Audi A5?

The MMI screen on my Audi A5 is unresponsive and won't turn on. What steps can I take to troubleshoot and potentially fix this issue?

First, try restarting your MMI system by holding down the power button for 10 seconds. If that doesn't work, try disconnecting the car battery for a few minutes and then reconnecting it.

If those steps don't work, it's possible that the MMI unit itself is malfunctioning. You may need to take your car to a certified Audi technician for further diagnosis and repair.

An alternative solution could be to check for any software updates for your MMI system. Sometimes updating the software can resolve any issues with the screen.
